I'm looking for a tool to make snapshots of the system with an ext4 system disk.

DD or CloneZilla. Both from live sessions.

Isn't disk cloning quite different from snapshot? I'm asking for learning purposes. I've used Clonezilla for a decade now and it has developed into a superior beast. None of the commercial products can beat it.

It is, but ext4 has no snapshot capability as far as I know.

It's worth the time to change to BTRFS. grub-btrfs is a life saver.

Assuming this is an option for you, convert your ext4 partition to btrfs (can be done without data loss) and enjoy having proper snapshot support. Timeshift makes it really easy to automate and manage btrfs snapshots.

LVM?

[-] bauve@jlai.lu 1 points 10 months ago

Yes it's on LVM but the system disk is ext4

but the file system is ext4, will it still work?

[-] Eikichi@lemmy.ml 3 points 10 months ago

It doesnt depend of your filesystem. Its a builtin in LVM.
So normally yes.

Thanks ๐Ÿ‘

You welcome l'ami,

dd is the tool you can use. But for a system disk you probably want to run it from a LiveOS

back in time? it uses rsync

[-] bauve@jlai.lu 0 points 10 months ago

Tools like rsync save only folders or files, but I want to save all system with Kernel, Drivers, ...

[-] Discover5164@lemm.ee 2 points 10 months ago

they are folders and files... no?
